I'm with Tanstaafl on this, for my needs anyway.

I have an FZ10 which I use for taking landscape photos and also zoom photos of birds / wildlife and I find it a pleasure to be able to do both without having to carry around and change another lens. Admittedly, most lighting conditions under which I am taking these photos are bright enough not to need the better low-light capability of a DSLR. I am also not turning my photos into poster sized prints, where the better picture quality of a DSLR would be required.

Also, given the mainly dry, dusty conditions here, it is a plus to me not having to worry about dust on the sensor when changing lenses.

I must say that I would like a faster autofocus though. The FZ50 (and any later models) would probably have this feature. Perhaps in the future I will upgrade to a newer super-zoom.

Re the viewfinder, the Panasonic super-zooms have one, albeit electronic.
